Thought I'd post a few of my initial, minimal post-processing (run through DxO, mostly the default settings, sometimes a little curves and a little playing saturation to pull back highlights or gain a little detail). This was my first big trip with my 5DII. Most of the shots were taken with the 24-105L, some with the 35L. I'm still sifting and perfecting some of the others and playing around with HDR/exposure merging.
First, a view from the top of the Drakensberg Escarpment in Mpumalanga:

Burke's Luck Potholes, same area, lovely colours and light:

Sunset from Constantia Neck. We'd just spent the entire day hiking Table Mountain, and made it down just in time to see the sun sink into the sea. Cropped some dead space above an below:
